ABSTRACT

The present invention relates to a toilet bowl including a rotary discharge pipe. A toilet bowl according to the present invention includes: a bowl on which a user sits; an outlet disposed behind the bowl; a discharge guide pipe communicating with the outlet, and connecting to a pipe embedded in a floor to discharge water; and a rotary discharge pipe having a discharge hole in the top thereof, and an inflow hole in an end thereof. According to the present invention, both the restoring force generated from a balancing structure of the rotary discharge pipe and torque generated from the kinetic energy of water (wastewater) discharged from the bowl are used to operate the rotary discharge pipe, thereby reducing the possibility of malfunction. In addition, since the toilet bowl has a simple structure, the manufacturing cost thereof can be decreased.

CROSS-REFERENCE TO RELATED APPLICATION

This Application is a Section 371 National Stage Application of International Application No. PCT/KR2011/008457, filed Nov. 8, 2011, the contents of which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to a toilet having a rotational drain means, and more particularly, to a toilet having a rotational drain means, which has a simple structure to reduce an amount of water used for washing a bowl of the toilet after a user uses the toilet.

2. Background Art

In general, a toilet includes a seat allowing a user to sit on it, and stores a prescribed amount of water therein and disposes of human waste by using water stored therein.

There are several prior arts related with such a toilet.

Korean Patent Nos. 10-0479678 and 10-0714959 respectively disclose toilets.

Such prior arts adopt a liftable operation system of a variable siphon tube including a bellows bladder and a bellows tube made of rubber, and a tension spring that are applied to a “variable siphon tube discharge system”.

In the conventional variable siphon tube discharge system, a variable siphon tube is connected to the rear of a bowl of a toilet by the media of the bellows tube made of rubber. In order to lift or fall the variable siphon tube, the bellow bladder made of rubber, which is expandable and contractable to temporarily store water therein, and the tension spring are provided.

The bellows bladder and the tension spring are means to lift and fall the variable siphon tube, and are requisitely mounted to the toilet even though there is the likelihood of system failure due to durability of the bellows bladder, the bellows tube and the tension spring because the variable siphon tube cannot be lifted and fall itself.

Because of its structural feature to repeat expansion and contraction, the variable siphon tube discharge system potentially has causes of system failure, and has a problem in that water introduced into the bellows bladder is wasted without being used to effectively clean the bowl because the water is discharged not to the bowl but to the variable siphon tube.

DISCLOSURE Technical Problem

Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a toilet having a rotational drain means, which can drain water (sewage) with sealability just by rotary power using kinetic energy generated while water introduced into a bowl is drained together with sewage through an outlet and by restoring force generated by a balancing structure formed on the outer face of the rotational drain means without using any forceful means, such as a bellows bladder, a bellow tube, a tension spring, and others, that may cause system failures, and which can allow all the water used for cleaning the toilet is drained through the bowl.

Technical Solution

To achieve the above objects, the present invention provides a toilet having a rotational drain means including: a bowl having a seat on which a user sits; an outlet formed at the rear of the bowl; a drain inducing tube communicating with the outlet and connected to a pipe line buried under the floor to drain water; and a rotational drain means located inside the drain inducing tube, the rotational drain means having an outflow hole and an inflow hole formed at both ends thereof, and a central shaft pin mounted on the other side so that the rotational drain means is rotationally mounted and connected on one side wall of the drain inducing tube, the inflow hole being communicatingly connected with the outlet.

The rotational drain means is formed in the Alphabet “L” in such a fashion that the outflow hole is formed at the upper end thereof and the inflow hole is formed at one end thereof, and has a balancing part of a predetermined weight is formed at a lower portion of a bent portion of the “L”-shaped drain tube.

A bulkhead is formed on an upper portion of the drain inducing tube and is spaced apart from the outflow hole of the rotational drain means at a predetermined interval.

A rise limit block and a fall limit block for limiting a rotational range of the rotational drain means are formed below the bulkhead.

A reserve water tank for temporarily storing some of water which is introduced into the bowl is formed above the bulkhead, and a supply tube communicatingly connected with the bowl is formed below the reserve water tank.

A connection tube is connected to a bushing hole formed inside the drain inducing tube, an end of the outlet is connected to the connection tube, and a clamp is mounted on the outer face of the connection tube to thereby provide sealability.

A preventive membrane is mounted on the portion where the inflow hole of the rotational drain means and the drain inducing tube are connected in order to prevent leakage of water.

A groove is formed on the outer circumference of the inflow hole of the rotational drain means, another groove is formed on the outer circumference of the bushing hole of the drain inducing tube, and the preventive membrane is rotatably fit to the groove of the inflow hole and the groove of the bushing hole.

Advantageous Effects

According to the present invention, the toilet having the rotational drain means is trouble-free because it is operated just by the restoring force by the balancing structure of the rotational drain means and by the rotary power using the kinetic energy generated while water (sewage) is drained from the bowl, and can provide a good cleaning effect because all the water used for cleaning is drained through the bowl of the toilet, and reduce manufacturing costs because its structure is simple.

As illustrated in FIGS. 1 to 6, the toilet 10 according to the present invention includes: a bowl 11 having a seat on which a user sits; an outlet 12 formed at the rear of the bowl 11; a drain inducing tube 200 communicating with the outlet 12 and connected to a pipe line buried under the floor to drain water; and a rotational drain means 101 located inside the drain inducing tube 200, the rotational drain means 101 having an outflow hole 101-1 formed in an upper end thereof, an inflow hole 101-2 formed in one end thereof in such a fashion that the inflow hole 101-2 is communicatingly connected with the outlet 12, and a central shaft pin 104 mounted on the other side so that the rotational drain means 101 is rotationally mounted and connected on one side wall of the drain inducing tube 200.

A connection tube 13 made of stainless steel or resin is fit to the outlet 12 formed at the rear of the bowl 11 of the toilet 10 and is fixed with a clamp 14, and then, an inlet 15 is perforated at a proper position of the rear of the bowl 11.

As described above, a drain system 100 having the rotational drain means 101 is formed at the rear of the bowl 11.

The rotational drain means 101 is formed in the Alphabet “L”. A shaft-mounted part 103 is protrudingly formed on an outer face of an “L”-shaped bend in a straight line from the center of the caliber of the inflow hole 101-2 which will be connected to the connection tube 13 of the bowl 11, and the central shaft pin 104 is inserted into a shaft hole 103-1 perforated at the center to a predetermined depth.

A groove 105-1 is formed in a predetermined portion of the outer circumference of the inflow hole 101-2, and a balancing part 102 is protrudingly formed on an outer face of the opposite side of the outflow hole 101-1 relative to the central shaft pin 104.

The balancing part 102 has weight enough to keep a state that the outflow hole 101-1 faces upwards when the rotational drain means 101 is connected to the connection tube 13 of the bowl 11 and the bowl 11 is filled with water for sealability.

That is, it is set that the balancing part 102 has a sufficient weight to prevent the rotational drain means 101 with sealability from being rotated before water is introduced into the bowl at once to clean the bowl 11.

In the meantime, the rotational drain means 101, which is located at the rear of the bowl 11 of the toilet 10 and will be connected to the connection tube 13, is rotatably mounted inside the drain inducing tube 200, and the drain inducing tube 200 induces water (sewage) discharged from the bowl 11 to the pipeline 20 buried under the floor.

The drain inducing tube 200 includes: a flange 200-1 formed at a proper position and having a round-shaped lower portion which is as large as it can be connected to the pipeline 20 buried under the floor; and a cone-shaped inducing ring 200-2 formed on the flange 200-1. A distance ranging from the bottom of the flange 200-1 to the bottom surface of a rim 10-1 of the bowl 11 corresponds to a height of the drain inducing tube 200. A reserve water tank inlet 210-1 is formed at a portion of the upper end of the drain inducing tube 200, which gets in contact with the rim 10-1 of the bowl 11, corresponding to a rim hole 10-2 of the rim 10-1, and a bulkhead 220 is formed and spaced apart from the reserve water tank inlet 210-1 at a predetermined interval to divide the drain inducing tube 200, so that a reserve water tank 210 is arranged in an upper space of the bulkhead 220. A supply tube 210-2 is additionally mounted below the reserve water tank 210 in a direction of the bowl 11.

The bulkhead 220 is provided to prevent a flick of water (sewage) discharged from the rotational drain means 101 and to help rotation of the rotational drain means 101 because the discharged water (sewage) is bumped against the bulkhead 220.

The drain inducing tube 200 further includes a bushing hole 200-3 formed in one side thereof so that the rotational drain means 101 can be introduced and rotated in the bushing hole 200-3. A protrusion having a predetermined width and a predetermined height is formed on the face of the drain inducing tube 200 around the bushing hole 200-3 and a groove 105-2 is formed on the outer circumference of the protrusion.

Below the bulkhead 220 which will be located above the drain inducing tube 200, a rise limit block 230 and a fall limit block 230-1, which will be described later, are respectively formed at proper locations.

The entire of the opposite side of the bushing hole 200-3 formed in the drain inducing tube 200 is removed, so that a space 200-5 to which a bulwark 240 is integrally fit is formed.

The bulwark 240 is fit to the space 200-5 and includes: a shaft mounting portion 240-2 formed in such a fashion that a certain portion of the inner and outer faces to which the central shaft pin 104 of the rotational drain means 101 is located is protruded convexly; and a shaft hole 240-1 formed from the inner face to a predetermined depth in such a fashion that the central shaft pin 104 can be inserted thereinto.

The rotational drain means 101 is arranged at the other side of bulwark 240 and is combined with the other end of the rotational drain means 101 by means of the central shaft pin 104.

An end of the rotational drain means 101 is rotatably fit to the bushing hole 200-3 in such a way as not to be fixed and not to be separated and has sealability.

In order to keep stability of the rotational drain means 101, the rotational drain means 101 requires durability, and for this, it is preferable that the rotational drain means 101 is made of a resin material.

One side of a preventive membrane 105 for preventing leakage of water is fit and fixed to the groove 105-1 formed around the inflow hole 101-2 of the rotational drain means 101, and then, the other side of the preventive membrane 105 is forcedly fit while the inflow hole 101-2 of the rotational drain means 101 is connected to the bushing hole 200-3 of the drain inducing tube 200.

Preferably, the preventive membrane 105 is made of rubber or resin that has good flexibility and durability.

Because a rotational range of the rotational drain means 101 does not exceed 90° and water pressure does not act, there is no influence on the lifespan of the preventive membrane 105.

Moreover, the preventive membrane 105 gets twisted according to the rotation of the rotational drain means 101, and hence, the preventive membrane 105 must have volume and flexibility enough to have no effect on the rotation.

After the rotational drain means 101 is seated on the bushing hole 200-3 of the drain inducing tube 200, the bulwark 240 is fit and fixed integrally to the space 200-5 of the drain inducing tube 200 so that the central shaft pin 104 of the rotational drain means 101 is inserted into the shaft hole 240-1 of the bulwark 240.

The drain inducing tube 200 gets near to the connection tube 13 at rear of the bowl 11, so that the outer face around the bushing hole 200-3 gets in contact with and is fixed to a bonding portion 13-1 of the connection tube 13.

Furthermore, the upper end surface of the reserve water tank 210 above the drain inducing tube 200 is also closely fixed to the bottom surface of the rim 10-1.

Additionally, the supply tube 210-2 of the reserve water tank 210 is connected to the inlet 15 of the bowl 11.

As described above, the drain system 100 having the rotational drain means 101 is disposed at the rear of the bowl 11.

A drain process of water stored in the toilet 10 according to the present invention will be described as follows.

Before operation, as shown in FIGS. 1, 3 and 6(A), in the toilet 10, the outlet 12 of the bowl 11 is joined with the rotational drain means 101 in order to keep sealability.

After a user uses the toilet, when a lid 10-4 of a water tank 10-3 is opened, as shown in FIGS. 2, 4 and 6(B), water is introduced into the bowl 11 and the reserve water tank 210 through the rim 10-1. The water introduced into the bowl 11 is drained through the outflow hole 101-1 after passing through the outlet 12 and the inflow hole 101-2 together with sewage inside the bowl 11, and in this instance, by means of kinetic energy, the rotational drain means 101 is rotated in a direction that water is drained.

The above operation is possible because the rotational drain means 101 is inclined to one side relative to the central shaft pin 104 due to the balancing part 102 of the rotational drain means 101 and the rise limit block 230.

Moreover, reaction generated while water (sewage) drained through the outflow hole 101-1 is bumped against the bulkhead 220 also helps the rotation of the rotational drain means 101.

As described above, the rotational drain means 101, which is rotated in the inclined direction by the kinetic energy generated when water (sewage) is drained, stops the rotation by the fall limit block 230-1, and in this condition, water (sewage) is drained. When a volume of drained water is reduced, the rotational drain means 101 is rotated in the opposite direction by means of weight of the balancing part 102 to be returned to its original position.

While the rotational drain means 101 is returned, because water contained in the reserve water tank 210 is continuously introduced into the bowl 11 through the supply tube 210-2, the outlet 12 of the bowl 11 and the rotational drain means 101 are filled with water, and hence, the rotational drain means 101 has sealability to thereby prevent a back flow of bad smells inside the pipeline.

While the present invention has been described with reference to the particular illustrative embodiment, it is not to be restricted by the embodiments but only by the appended claims. It will be understood that the exemplary embodiment of the present invention is to cover all modifications, equivalents, and alternatives falling within the claims of the present invention.
